This reverts commit fa9463564e77067df81b0b8dec91adbbbc47bfb4. Per Linus Walleij: Dear ARM SoC maintainers, can you please revert this patch. It was the wrong solution to the wrong problem, and I must have acted in stress. Andrey fixed the real bug in a proper way in these commits: commit e5545c94e43b8f6599ffc01df8d1aedf18ee912a "gpio: of: Check propname before applying "cs-gpios" quirks" commit 7ce40277bf848391705011ba37eac2e377cbd9e6 "gpio: of: Check for "spi-cs-high" in child instead of parent node" Signed-off-by: Olof Johansson

syscalls: Remove start and number from syscall_set_arguments() args

2019-04-05T13:27:23Z

After removing the start and count arguments of syscall_get_arguments() it seems reasonable to remove them from syscall_set_arguments(). Note, as of today, there are no users of syscall_set_arguments(). But we are told that there will be soon. But for now, at least make it consistent with syscall_get_arguments().

syscalls: Remove start and number from syscall_get_arguments() args

2019-04-05T13:26:43Z

At Linux Plumbers, Andy Lutomirski approached me and pointed out that the function call syscall_get_arguments() implemented in x86 was horribly written and not optimized for the standard case of passing in 0 and 6 for the starting index and the number of system calls to get. When looking at all the users of this function, I discovered that all instances pass in only 0 and 6 for these arguments. Instead of having this function handle different cases that are never used, simply rewrite it to return the first 6 arguments of a system call. This should help out the performance of tracing system calls by ptrace, ftrace and perf.
